CMake error - Could not find package configuration file for "librealsense2"

[Sammysedo]

Hello,

I have ROS2 Foxy built from source on Windows 10 and I'm having trouble building the ros2_intel_realsense package. I built librealsense2 from source (since I previously had compatibility issues with the binary version on Python 3.8), using instructions from here and here. The python libraries are now working:

Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyrealsense2 as rs
>>>                           

However, I am not able to build the ros2 package, instead I am getting a CMake error:

C:\sample_ws>colcon build --merge-install

CMake Error at CMakeLists.txt:65 (find_package):
  By not providing "Findlibrealsense2.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "librealsense2", but CMake did not find one.

  Could not find a package configuration file provided by "librealsense2"
  with any of the following names:

    librealsense2Config.cmake
    librealsense2-config.cmake

  Add the installation prefix of "librealsense2" to CMAKE_PREFIX_PATH or set
  "librealsense2_DIR" to a directory containing one of the above files.  If
  "librealsense2" provides a separate development package or SDK, be sure it
  has been installed.

Summary: 10 packages finished [30.2s]
  1 package failed: realsense_ros2_camera
  1 package had stderr output: realsense_ros2_camera

It seems that CMake is unable to locate my build of librealsense2. I am unable to locate librealsense2Config.cmake or librealsense2-config.cmake anywhere in my build directory. I have rebuilt several times with ALL_BUILD and it's always the same error. I have tried setting librealsense2_DIR to the root directory but it seems to fail. Any ideas?

• Python 3.8
• CMake 3.18.2
• ROS2 Foxy
• Windows 10

I'm experiencing this error as well, any update?
